The front legs were also radiographed in order to evaluate the curvature of the radius and ulna. Calcified discs were found in 75.9% of the longhaired miniature dachshunds and in 86.7% of the wirehaired ones. The occurrence of signs associated with IDD was 16.5% in longhaired and 15.6% in wirehaired miniature dachshunds. The occurrence of signs of IDD in dogs with calcified discs was 20.0% and 17.9% in longhaired and wirehaired miniature dachshunds, respectively. In dogs without calcifications only one dog showed signs of IDD. The curvature of the radius and the ulna did not differ between the dogs with signs of IDD and the healthy ones, or between the dogs with and without intervertebral calcifications. Our results indicate that radiographic eradication based on the presence of intervertebral calcifications is not suitable for breeding purposes for the Finnish miniature dachshund population because the percentage of dogs without calcifications is small.

The nature and content of intellectual property (IP) law, which is heavily contingent on the state of technology and on social and market developments, has always been subject to ongoing transitions. How those transitions are effected and the shape they take is crucial to the ability of IP to achieve its stated goals and provide the necessary climate for investment in creativity, innovation and brand differentiation. Yet the need for change can run headlong into a desire for coherence. A search for coherence tests the limits of the concept of “intellectual property,” is imperiled by overlaps between different IP regimes, and calls for a unifying normative theme. This volume assembles contributors from across IP and the globe to explore these questions, including whether coherence is desirable. It should be read by anyone interested in understanding the conceptual underpinnings of one of the most important and dynamic areas of the law.
